Furthermore, the seismic hazard and risk provided may not represent the best available science. For example, although ground motions with 10, 5, and 2 percent probability of exceedance (PE) in 50 years have been said to represent the best available science, they are hard to explain and understand. The methodology used to derive those ground motions has been found to be inconsistent with modern earthquake science. In other words, the ground motions with 10, 5, and 2 percent PE in 50 years do not represent the best available science and are neither seismic hazard nor risk. Clearly, there is a gap between engineers and seismologists in defining and understanding seismic hazard and risk. This gap has hindered development of more cost-effective policy and engineering design in the United States, as well as in other countries. The consequence is obvious.
